Update 2020

After using the matrix for several years and supporting many other person to realize their own version, it is time to update my matrix based on all the learning from the last years. So now it has the following features:

Replacing the old Raspberry Pi A+ with a Pi Zero W

Removing the Arduino board and just driving the WS2812B LEDs with the Pi

Using a Bluetooth gamepad instead of the large WiFi-Controller

Using inbuilt Bluetooth and WiFi from the Pi

Updating all used Python libs to the latest state

Adding new features to the software:

Auto-connect to the gamepad, reconnect when switched off and on

Shutdown the Pi via gamepad

Highscore for Tetris and Snake

Improved gameplay

Adapt the simulator to the new input device

So it should be easier now to rebuild the matrix using available components and latest libs. Therefore I wrote an instructable to provide a step-by-step guide to build your own matrix. It is also planned to offer a set with the main components like wood veneer and laser cut parts on Tindie soon. So stay tuned and enjoy making ;-)
